Re: VS 2010 Panel with AutoScroll=true : Horizontal Scrollbar does not appear - Windows Forms Discussion Boards

Hello folks,

There is a UserControl (MyUserControl) that contains a container control (MainGroupBox) on it's surface (Dock.Fill). The question is how to place controls on MainGroupBox when user drags them into the MyUserControl in Design mode. I marked MyUserControl with ParentControlDesigner attribute. Now it accepts controls but places them behind the MainGroupBox. I tried to remove controls from MyUserControl and place them into MainGroupBox on ControlAdded event, but it seems it doesn't help.
I tired in vain to solve the problem from last weekend Frown | :(

Does anyone know the solution? Any suggestions?

Thank you in advance.

Everything is possible!

Hmm... I think that I see work-around here.
We can tune z-index of MainGroupBox in order to show it behind all other controls like following:

private void CheckableGroupBox_ControlAdded(object sender, ControlEventArgs e)
{
    gbMain.SendToBack();
}

But it is a trick, and controls' nesting is still wrong.

Everything is possible!

Dear All,
Am Using Epson BA-T500 printer. Manufacturer has provided a dll to print but its printing for arabic only question mark. but manufacturer has sent me a testing tool, its printing arabic correctly. I am coding in Vb.net 2005. so please let me know your ideas.

Thanks a lot

Regards
Azeem

If the printer is working with the test tool then look into your delivery of the data, make sure all the data is Nvarchar etc.

Never underestimate the power of human stupidity

Its is not nvarchar but string.
I can able to display the arabic text in a message box

Regards

Please see my reply to Henry Minute for a more detailed analysis of the behavior and a work-around.

Hi,

[Edit #1]
Context : inside a SplitContainer SplitPanel (Panel1) is a Panel (the "Host Panel") which at run-time has other Panels added to it whose height and width may vary. The Host Panel has "Auto-Scroll" set to 'True.
[/Edit #1]

The Vertical Scrollbar appears okay when I put panels inside the Host Panel at run-time and the vertical space used exceeds the Host Panel's height.

But, the Horizontal Scrollbar just won't appear as expected when I put in Panels wider than the Host Panel's horizontal size.

I have tried explicit calls to set the HorizontalScroll Enabled and Visible properties in code with no success :

hostPanel.HorizontalScroll.Enabled = true;
hostPanel.HorizontalScroll.Visible = true;

I did some Googling, and searching here on CP on this, and it looks like a few years ago some folks had some probem with the HScrollbar not showing up if the Panel was docked to an enclosing Form or other Container. Appears that a few years ago many people were having the problem of having the scrollbars on a panel show up when they wanted them hidden Smile | :)

I found this KB[^] at Microsoft :

"Article ID: 908536 - Last Review: August 29, 2007 - Revision: 2.2
The horizontal scroll bar that is used in forms may not respond to mouse controls or actions when you use themes on a Windows XP SP2-based computer"

But that's from 2007 : surely that issue is not still open now (?).

There's an old CP article that uses Interop API calls control Panel scrolling, but I don't want to go there, either.

So I tried every combination of Docking and Anchoring I could think of, including "None" for both Dock and Anchor properties. I tried it with the Panel set to have a very large Maximum size, and a Maximum size set to its initial size at design-time. No change in behavior. I also experimented with setting AutoScroll on the SplitContainer to True and False and observed no change on the Host Panel.

Appreciate any ideas.

thanks, Bill

Just a thought. Some time ago I had similar problems (which automagically resolved themselves when I wasn't looking). If I remember correctly my temporary solution involved setting the AutoscrollMargin. Have you tried that?

Summary : turns out the problem was with the side-effects of using Dock = DockStyle.Fill on my Row Panels. Whether this is VS 2010 or me : don't know (my machine with VS 2008 is down). Fix turned out to be pretty easy : just manually set the tops of the Row Panel objects.

In fact I did play with both AutoScrollMargin and AutoScrollMinSize properties; tried setting them both 32,32, setting them both to 64,64, as well using them at their default values of 0,0 : no change in behavior in my panel.

So then I thought maybe the problem is related to the fact the Panel is being hosted inside a Panel of a SplitContainer. So I took the main panel out of the SplitContainer and put it directly on the form : same result.

So I set up a test program : no problem forcing horizontal scrollbars to appear with a Panel on the Form or inside one of the Panels of a SplitContainer !

Back to the drawing board : I discovered that what is suppressing the display of the Horizontal Scrollbar is setting the Dock property of the newly constructed Row Panel object (containing a bunch of Column Panel objects) to 'Top.

By taking out the call to set DockStyle to 'Top : the Horizontal scroll bar appears : of course then all the Row Panels appear on top of each other !

So I tried hard-coding setting the Row Panels height and width after using 'Dock, as well as before : no change. I experimented with many variations of setting Dock before and after adding the Row Panel object to the top-level container Panel, etc. No difference.

Seems like whenever I use Dock (followed by 'BringToFront) to cause correct vertical display of the Row Panel objects : it over-rides the width of the RowPanel object and sets it to the size of the container Panel.

Here's a hierarchy of what I am doing :

Outer Container Panel
Row Panel 1
Columm Panel 1
Column Panel 2
Row Panel 2

And so forth. Inside the Row Panel the Column Panels are docked Left.

best, Bill

Well, about a month ago I posted a question in this forum because I ran into a massive problem in my program. I had over a hundred icons in 2 toolStrips. And then out of nowhere, for no particular reason, I opened Vis. Studio the next day to find that all of those Icons had dissappeared. No errors while debugging or anything. I could still click where the Icons should've been, and the program would perform the specified task, but the icons were just gone. And it's just recently happened again.

In short. Atleast, In my situation, this was caused by duplicate resources. I have no idea how it happened. But I removed sll the resources and then re-added them again and all is fine.

jase.

P.S. I remember telling somebody that I would post my findings, but I couldn't find my original post so I decided to create a new one.

Yay! problem solved lol

Hello,

I am geeting error say "syntax error (missing operator) in query expression 'ShipmentAdvice.Ship_Code=ConditionMst.Con_No ON ConditionMst.Mode='SHIP'.

Please help me.
Thank you in advance.

This is a SQL problem and not in any way related to Windows Forms so you are in the wrong forum.

To debug SQL problems you execute the SQL statement in a Database Tool rather than from your program.

Using Access is a poor decision. You should look into using SQL Express[^]

Thanks for yr suggestion , sorry i am in the wrong forum.

Hi all.

I am currently doing the following to load my data sources from DLL's.

I have a DLL with 3 datasets and various datatables and tableadapters. I get a list of these through the following
Dim Assem As Assembly = Assembly.LoadFile(AssemFilename)
Dim AssemTypes() As System.Type = Assem.GetTypes

Now I can create an Object to one of these tableadapters like this
Dim TAType As Type = Assem.GetType(t)
Dim TAObj As Object = Activator.CreateInstance(TAType)

and I can use that object to retrieve data from the database.
Dim result As Object = CallByName(Obj, "GetData", CallType.Method, Nothing)

My problem is, I want to know what commands (Fill, FillBySurname, FillByCode) etc are on the TableAdapter (TAObj Above). Or at least to get the SQL commands so that I can set any parameters required in the CALLBYNAME command above.

Many thanks for any assistance.

I am trying to run an application on a machine that does not have Visual Studio 2008 installed.
I am getting an error message "This application has failed to start because the application configuration is incorrect. Reinstalling the application may fix the problem."

I have installed the distributable libraries on this machine. I have compiled my code under release mode. Update the machine with all patches from Microsoft update as well.

I used the setup and deployment wizard too to see if that would solve my problem.

What else could I have missed?

Can someone please help.

Umm does the client machine have the .net framework installed (the proper version of it as well)?

Check out the CodeProject forum Guidelines[^]

Yes.

If this helps, it's just a plain dialog based application.

Being curious, I created an application using the wizard, and tried it on the machine. Same result.

ok. fine i m giving the code for restrict the no of copies of print dialog.
if (ds.Tables[0].Rows.Count > 0)
{
cmd = new MySqlCommand("select credencials.Limit-credencials.`No of Pages` from credencials where UserName='" + txtusername.Text + "' and Password='" + txtpassword.Text + "'", con);
{
adp = new MySqlDataAdapter(cmd);
ds = new DataSet();
adp.Fill(ds);
PrintDialog dia = new PrintDialog();
dia.PrinterSettings = ps;
if (dia.ShowDialog() == DialogResult.OK)
{
timer1.Dispose();
Copies = ps.Copies;
Copies = (short)(Copies * job.NumberOfPages);
if (Copies >= Convert.ToInt32(ds.Tables[0].Rows[0][0].ToString()))
{

MessageBox.Show("Exceed Printing Limit is " + Copies.ToString());
dia.ShowDialog();
timer1.Dispose();
job.Resume();
this.Hide();

}
else
{
timer1.Dispose();
job.Resume();
this.Hide();
}
using this code u can restrict the no of copies of print dialog with ur database copies.
takecare.
Thumbs Up | :thumbsup:

bye.
